19 Claims.

The invention concerns mechanism for. making open work designs in fabric produced on knitting machines and in which the designs may be-varied according to the setting of controlling elements on a lace wheel or like carrier 'called into action by a cam on the main cam shaft when this is shogged into narrowing position.

` The invention concerns also means by which in addition to the open work, by which the fabric may present ornamental designs, other open work areas may be formed giving, for instance, `the gauge of the fabric `and other data of a utilitarian character such as the number of yarns used in the formation of the stocking blank.

The invention consists in the features and combination and arrangement of parts hereinafter described and particularly pointed out in the appended claims.

In the drawings `Figure l is a front view of a portion of a full fashioned knitting machine generally of the single head type such as is disclosed in Letters Patent of the United States granted to Howie et al. on December 4, 1934, No. 1,982,991, though it will be understood that the invention is not restricted in its application to any particular type of full fashioned machine, whether of the multiple head type or single head type. Nor is the invention restricted to whether or not the machine is of the single unit type. Some of the mechanism ordinarilyl employed in a full fashioned knitting machine. though used in my machine as in prior practice, is not illustrated or described herein, because those skilled in this art will understand the construction and operation of my improvements without a disclosure` herein of those old features.

193s, serial No.n 184,4t5

(c1. ees-0s) duced at any particular point or 'points across 15 the fabric.

I employ and control a lace bar whose points are disposed at locations along said bar at distances apart suillci nt to permit variations in the design by automat, cally adjusting the said lace bar to make its points cooperate, according to the prescribed pattern, with various needles of predetermined sections of the needle row. Thus, as an example, the transfer points of the lace bar may be separated fromv each other a distance equal to sixteen needle spaces, the position of the bar being determined by pins of various lengths in a lace or pattern member associated with the lace bar, said pins being set in predetermined positions according to the prescribed pattern and being controlled by connections extending from the cam shaft A of the machine.

One example of designs that may be made is as follows: After making the picot edge at the 'turn of the welt a series of holes may be made in the fabric representing, for instance, the sign A3--45 readable in the direction of the length of the knitted wales. t

The numeral 45 would indicate the gauge and the `numeral 3 would indicate the number of the yarn used in knitting the fabric. Following the formation of the welt, andimmediately below the same, the design in the single layer of fabric may assume various patterns. As an instance there may be rows of holes extending in the direction of the course of knitting, i. e. across the These rows of holes would be parallel and spaced apart in the direction of the length of the fabric and between them the design, as an instance, may include rows of holes extending diagonally .of the fabric either simply parallel with each other, or crossing each other to produce a diamond shaped form of design, and these rows of holes may be interspersedwith segregated holes.

The sign made up of the numeral 3, the dash and the numeral 45 or other insignia, is made by 'a special one of the picot points which is maintained in position to cooperate with a limited number of needles of the needle row while 60 the remaining transfer points a1 of the picot or lace bar are dropped back out of operation relative to the needles. This special picot or transfer point is shown at a. More than one of these special points may be employed to make signs or insignias at various segregated restricted area located at various points acrossthe fabric.

When rows' of openings are to be made in the fabric such as picot or lace work using all of the transfer points, namely, the special point or points a and all of the usual points a1, then the picot vbar is moved forwardly from the position shown in Fig. 4 to a position in which all of the transfer points al are in the same vertical plane with the special point or points aA which latter then become one of the row of evenly spaced transfer pointsfor making picot or lace work.

For setting the picot or lace bar I to make available either the insignia point or points a or the row of picot or lace points a1 the following mechanism is employed; a shiftable cam bar a2 is slidable lengthwise leftward Fig. 3 through suitable bearings, such asqat a3, and in doing so will be moved towards the Vfront of the machine by the inclined cam surfaced4 thereon working I against the adjacent edgebf the bearing a3.

'I'his movement ofthefc'am 'bar will move the picot bar from theposit'ion shown in Fig. 4 where the picot points a1 ,arey idle to a position where they will occupy ythe'irworkin'g position relative to the needlesjand in' which position they will line up with ythe `special point or points a to form a complete unbroken row of transfer points. f

For this positioning of the picot bar by the cam bar a2 adjusting screws a5 Fig. 5 are mounted in the hangers 3 of the picot bar and bear upon thefront face of the slidable cam bar a2 so thatr as ,thef'slide bar moves bodily forward and backward, i. e. in a direction transverse to its length, the picot bar willbe adjusted accordingly, and by adjusting the screw or screws'a5 accurate setting of the picot bar relative to the needles will vbe attained. The cam bar a3 has a roller aFig. 3 contacted by an inclined face b1 of va cam track arm b pivoted at b2 to a ixed frame, member t, Figs. 2 and 7 and moved to operative position by arm b4 of a lever pivoted t6y the'frame at b5, the other arm b of said' lever-bearing on the edge of a cam disc c having high and low surfaces c1, c2, said disc being fixed on the hub 26, Fig, 3, having' a drive t with the hub 26| of the pattern wheel 26. 'I'his cam disc is made of two parts held together by screws c3 Fig. 3 passing through slots into the hub 26'. The sliding cam bar a2 is guided by a tongue and groove connection at aI Figs. 1 and 3.

.When the lever arm b6 is riding the high surfac c1, of the cam disc c the cam arm b is main-l tained in operative position relative to the roller a. of the cam rod a2 and consequently during the narowing dip of the narrowing frame l1 the cam bar a2 is moved leftward, it being understood l that said cambar is carried by the narrowingv frame and hence the cam incline a4, of which .there may be a number distributed along the "cam bar, will cause' the said bar to be moved at right nagles to its longitudinal axis, or bodily towards the -front of the machine, and hence through the adjustment screws a one of which is shown in Fig. 5 the picot bar will be moved forward i. e. towards the front of the machine to set the picot or lace points a1 in cooperative -relation to the special point or points a to take o!! loops from the needles and replant them on other needles for making the prescribed design by leaving openings in the fabric at the prescribed locations.

On the other hand, while the said lever l)s is riding on the low cam edge c2 of cam c'the inclined cam portion bl of the cam arm b is positioned out of line with the roller a of the cam bar a2, this effect being due to the spring b'f drawing the said cam arm b aside from the path of the roller a8 as this moves downwardly with the narrowing frame to bring its stop bs against liframe stop b9 Figs. 2 and 7. This allows the said ycam bar a2 to remain in its extreme right hand and rearwardl position of Fig. 3 with those points a'1 of the picotor lace bar out of working relation to' the needles as in Fig. 4. This cam bar a2 is subjected to the action of spring ax Fig. l, which stresses it rightward in the position shown in Fig. 3, and also to the action of a plurality of springs, one of which is shown at ay in Fig. 3, which press said bar rearwardly to' inoperative position when the cam incline a.4 of the bar is no longer contacting the edge of bearing a3 and .the picot bar will Lthen assume its rearward fposi'tion relative to the needles at which the picot points al will be in inoperative position, whereas the special point or points a will maintain its or Vtheir operative position relative to the needles.

' The special transfer point or points are mounted on a hanger `d pivoted`at its upper end at d1 Figs. 4 and 6 to a brackets d? fixed to the picot bar.

The hanger 4d is provided with adjustment screws, the lower one d3, Fig. 6 contacts the face of picot bar to accurately adjust its relation to the special picot point a so that when the picot bar is in its forward position, its points a1 will align with the said point a to-provide a complete series of points equally spaced apart along the bar and all in the same relation to their respective needles. The upper adjustment screws .d4 of the said hanger d contacts a wear plate plate d5 mounted on the xed bar d@ of the narrowing frame, which sets the special transfer point, or points, if more than one is used, in proper positon relative to the needles, under pressure of the leaf spring d7 atall times.

The hanger 'd of the special transfer point is pressed to proper positon relative to the bracket d2 upon which it is pivoted and guided by the use of laminated leaf spring d'1.

The operation of one' complete cycle of the narrowing head necessary to produce a given hole or set of holes in the design required is as follows:

With the picot bar, through its associated mechanism, resting against a pin in the pattern wheel 26, and the cam lever b in a position whereby the roller as on the end of the movable bar a2 has contacted therewith, hence placing the complete picot bar with all its points in an operative position; the narrowing mechanism is tripped by the usual narrowing button on the regular pattern chain, causing the main cam shaft to be shogged into narowing position; and the narowing head to make its first dip, bringing the points of the picot bar, then in operative position, into a position to receive the loops from the rneedles which the particular length pin in the pattern wheel calls for. The loops having been received by the picot points from their respective needles, the narrowing head is raised to a point to permit the free passage of the points over the knock-over bits to accomplish the cross-over from the needle from which loop is to be delivered. This delivery having .been made, on the second dip of the narrowing head.\it (the narowing head) is `now ready to make it up or final movement of the cycle.

During this upward movement, after the picot points have beenv suiliciently raised to not meet any obstruction from the knock over bits or singers, the picot bar, through the yoke I8, mounted on the vertical shaft, and other assoelated mechanism, is moved into its extreme left hand position, after which the indexing ofthe pattern wheel occurs, bringing the next pin in the series into line with the plunger which controls the position of the picot bar on`its next dip.

It is understood -that whethery a single o r successive dips of the narrowing head are desired, this control wouldbe obtained bythe arrangement of the narrowing buttons on thepattern chain, and that after a single ormultiple number of dipshave been accomplished, the main cam shaft is returned to its` normal or regular knitting position.

'I'he movements of the narrowing head, 'when special point or points, only, are in operative position are identical with those above described, with the exception of the position of the cammed lever b,mounted on the housing, which is withheld from its position where it contacts the roller a6 on the end of the movable bar a2, thereby this bar'remains in its back position, in turnfhold- `ing theregular points offfthe picot bar inan inoperative position.

The lace or picotv bar I carries the lace or,V picot points comparatively widely spaced apart, for instance, sixteen needle spaces, clamped in place by a section 2 againstthe main part ofthe bar. This bar is carried by arms 3 clamped by screws 4 to a rod 5 pivotally and slidably mounted in bearings G of the narrowing frame comprising arms 41 similarly numbered in said patent and likewise pivotally mounted as usual to the rear part of the frame of the machine to have up and down swinging movement, which is imparted thereto by links 41a and lever arms 41b as in usual practice. The picot or lace bar is stressed by` a spring 1 to move to the right, Fig. 1 when .freeto do so, said spring bearing at one end on apart of the arm 8 in which the rod 5 is free to slide and turn. This arm 8 is fixed to a frame rod 9, vfixed in the narrowingv frame. The spring A1at its other end bears on a collar vIll fixed tosaid lod 5. The rod 5 also has` an arm II fixed theretoV which carries a finger or `projection I2 contacunga plate I3 on a plunger or rod I4 mounted slidably through a bearing I on thefixed frame, and stressed rightward by aspring I4, Vguided by a pin 14h, Figs, 1, 3 and '7, and having a pro-V jection or finger I6, adaptedtobe contacted by a projection I1 on a yoke Ihaving aniupperfarm` and a lower arm I8, connected together' as shown in Fig. 2 by a vertical portion I8b. yokeis loosely mounted to` turn `on the vertical shaft 20. ,The lower arm I8?I of said yoke has connected ,thereto pivotally lalirik 2|, said link being pivoted: to a lever 22`ypivoted`tofthe frame at 23 and operated acam'2l yon the 'main cam` shaft. v

r`By this'mechanism the picot bar is given a movement leftward .Fig..l1 preparatory to the `par-- ticularsetting or position it is to assume under the action of thev` spring 1,pre ssing.it rightwardV in Fig. 1 against one of a series ,of stop pins 25 adjustably mounted in a lace or pattern Vmember 26, preferably in the form of a wheel. This wheel is turnable step by step about an axle 21. The indexing of this lace pattern wheel .takes place while vthev picot or lace bar I is at the extreme leftward limit of its` movement,l viewed from the front of the machine, Fig. l. n

This wheel 26 has a ratchet, portion 28 and a. series of openings corresponding to the number of ratchet teeth. These openings receive the pins 25 which are of varying lengths according to the pattern Ato be formed in the knitted fabric, and they extend with their :axes parallel withthe axis of the pattern wheel. l

'I'hey are Vbrought in succession by thestep by step rotary movement of the patternwheel to a point where they are in line with a tooth or .projectio'n 30 on plunger or rod Il so that when the picot bar returns inthe right hand direction, Fig. 1, by thev spring 1, after having been moved as above'stated. to its extreme leitward position,

it will bearrested by` contacting theactive pat-` tern pin '25 of the lace' wheel which, according to the prescribed plan is nowin position opposite the projection 30 above mentioned on theplunger I4, and thus bythe stopping of. this plunger Il will, 'through the connections before described. i. e. plate I3, adjustable finger I2, bracket or arm II and picot bar carryingrod 5, the picot bar will be arrested and its position in relation to the needles wil be determined according to the pattern prescribed by the variouslengths of pins 2 ofthe lace wheel. n ,f .f

'The ,pins 25 are. slidably. mounted in the lace or pattern Wheel,25.andthemovement` of the pins towards the right Fig. 3 is limited by contact of said pin with a lever 3| loosely mounted toturn about the shaft`20 and having an end 32 provided with an ,adjustable stop screw 33 adapted to bear on a fixed part of the structure such as the bracket 34 which supports the patternmem ber or wheel and associatedparts. 4Thusthe position of the active pin or the pin which for the time being is acting as a stop for determining theI rightward position of thepicot or lace bar, and consequently the lace bar isfaccurately positioned.

The position of the ,picot bar alongthe needle row to make its points register with vparticular needles according to tliepattern having been determined by the pattern pin of the lace wheel acting as a stop for saidlaceor picot bar,. the fashioning frame is now ready to make` its first dip for` taking off loops from the needlesaccording to the prescribed plan so that these loops r'can be transferred along the needle, row and deposited on other needles leaving thoseneedles. from which loops have beenv taken, bare or devoid lof loops, thus to leave openings inthe fabric -for producing the designi desired.Y Desirably4 this shifting of the loops along the needle row and their deposition upon other needles takes.l place, in the form of ,the invention shown as illustrative of its prinoiplesrmpon.the-needles adjacent those from VVwhichthe loops have been taken by the picot or lace points. f1

( ThisV one needle movement `of thepicot orlace banfis derived from a cam 2|a at the Aextreme righthand end of the ,main cam shaitA,V Fig. 1 whenfsafidjshaft, as is usual in ordinarylpractice, is shogged into position for narrowing. cani operates a lever 35, Fig. 2 ,.pivotally .mounted on the ordinary rock shaft 36 and connected Aby a link 31, whiohginturnvis connected to a bellicrank the movement of the pattern pins of the lace or picot pattern wheel. The operation of the vertical shaft 2,0 as just described, effects the shifting of the picot bar one needle space through the medium of its upper arm 42 acting through the lever 3|, the slidable vpattern pin 25, and the connections operated thereby leading to the bar carrying the lace points.

For indexing the lace or pattern wheel 26 step by step a pawl 44 engages the ratchet teeth 28 of the lace wheel. 'I'his pawl is pivotally mounted at 44 on an arm 45 pivoted at 45 to the pattern wheelbracket34. The pawl is held yieldingly in engagementv with the ratchet wheel by a spring 4G,

Thispawl carrying arm is operated by an arm 4| fixed on the vertical shaft 20 and a spring B, Fig. 2a. vThe indexing of the pattern wheel occurs during the return movement of the vertical shaft, and while the treme position to the left.

' The dips ofthe narrowing frame are the regular ones well known in the art, brought on by the usual pattern chain, which also initiates the shogging of .the main cam shaft at the periods needed, and it will be understood that the lace mechanism described herein functions in -timed relation therewith.

The picot or lace bar of the present invention .lis mounted on the regular narrowing frame having the usual narrowing movements, being brought into action as usual by buttons on the pattern chain. l f

vWith the particular pattern mechanism shown herein the first operation that takes place in connection with the picot or lace bar is the formation of the usual picot at the turn of the welt. Due to the particular degree of spacing of the picot or lace points as disclosedy herein the picot is formed by eight successive dips of the narrowing machine. l f

After the welt is turned the lace design is produced. -This may consist of spaced apart rows of holes like those occurring at the picot line,- and between these two rows of closely set holes,

' the design may consist, for instance, of diagonal rows of holes i. e. at an inclination to the wales 'and spaced apart across the fabric. This design is made by two successive dips of the narrowing frame for each line of holes in any given course, due to the points being spaced sixteen needles apart on the lace bar and the holes only eightneedles apart, the relative position of the holes being predetermined by the lengths of the pins in the. pattern wheel. The same principles apply to other forms of design, for instance, with rows of holes extending diagonally of the fabric and crossing each other. A

The picot bar is held in proper .relation to the slidable cam bar by a keeper Figs. 1 and 8,

consisting of a small plate 49 having a fingerpiece 50 by which it maybe raised to release the picot bar, so that the latter maybe swung up to the idleposition around the vaxis ofV the-'rod i 5,fFigs. '1, 4,- 5 and 8.;

This `keeper has a vertical s'lot 5| which will enable it to be raised, and a leaf spring applies.

retaining pressure to this keeper to hold it in picot bar is atv its exlifted positionto enable the picot bar to bey When the keeper is in its low positionthe picot g bar and the cam bar a2 are virtually connected by the bracket 53 to move backwardly as one body under the pressure of the springs ay and the points a1 will then occupy the position shown in Fig. 4.

In Fig. 8 is shown a stationary cam member a3A like that shown in Fig. 3 for moving the cam bar a2 laterally of itself forward or backward when said cam bar is moved lengthwise. This cam is fixed to the frame bar d6 by a screw 56 passing through a member 51 on the front side of the frame bary d6. This member has a hollow boss 58 in which there is a spring pressed button like that at ay Fig. 3 for pressing the cani bar rearwardly and act as detaining means for said bar.

The invention is not limited in itsaapplication to full fashioned machines as it may be employed for making only the upper part of the stocking blank.

Neither is the invention limited to the employment of the special loop lifting point as the.

row of points may be made up of a complete set of points all fixed in alignment in the picot or ious positions with those of the needles, sinkersand knock over bits is like that of the narrowing points during a narrowing operation and are disclosed in Fig. 9 to Fig. 17 inclusive. At Fig.

9 we see the picot point a1 in its extreme up position and the needle in the position where yarn is being delivered, prior to knitting the next fabric course, the knitted fabric laying on top of knock over bits and under sinker. After this new course has been knit and the narrowing head tripped, the narrowing head dropping faster than the needle bar, `we iind the needle and picot point each partly buried in the others eye as shown in Fig. 10 which permits both to pass through last loop of fabric on needle as shown in Fig. 11, after which needle bar'continues to drop withdrawing the needle from the fabric which is now held by picot point, see Fig. 12. Both the needle and the picot point are then raised, sinkers being withdrawn, until point of the picot point clears the top of the knock over bit as shown in Fig. 13, this clearance permitting the point a1 to be shifted laterally to the adjacent needle to the left, after which as 1n Fig. 14, both needles and picot points are ready to make the downward stroke when the needle and the point again embrace as shown in Fig. 15 and the sinker comes forward ready to strip the fabric from the points onto the needle adjacent to one from which the loop was originally taken. 'I'he picot points are then raised to the extreme up position'and the needle bar more slowly raises .toward its up position as shown by Figs. 16 and 17,
